Distribution Holes/Notches: Diameter/Range 5-50 mm

Component Specifications

Definition

Distribution holes/notches are strategically designed apertures or cutouts in the surface of distribution troughs or pans, engineered to regulate the passage, segregation, and directional flow of bulk materials, powders, granules, or components. These features ensure uniform distribution, prevent clogging, and maintain process efficiency in automated systems.

Working Principle

They operate by allowing materials to pass through or be diverted based on size, shape, or flow characteristics, utilizing gravity, vibration, or mechanical force to achieve controlled distribution, sorting, or separation within industrial equipment.

Materials

Typically made from stainless steel (e.g., AISI 304, 316), carbon steel, aluminum alloys, or wear-resistant polymers (e.g., UHMW-PE, PTFE), chosen for corrosion resistance, durability, and compatibility with processed materials.
